There’s no Hitler-rights lobby to protest. But there’s a big mishkav zochor lobby.
Incidentally, if the OU refused the hechsher and one thing led to another and they went out of business, there’d be a host of other hechsherim waiting to take their place for all products around the world. So it’s really more of a business decision, rather than “the end of kashrus as we know it.” The OU like to pretend that they’re the be all and end all. They almost are, bemetzius, but if they disappeared there’d be a quick replacement.
